"Astronomers have found an icy miniplanet that orbits the sun well
beyond Pluto, providing evidence that the solar system extends much farther
than was once thought...."

This new body's discovery position turned out to be approximately 3 Taurus 08.
CHIRON WAS DISCOVERED WHEN IT WAS AT 3 TAURUS
08!
This links this new trans-Plutonian body,
15874 (1996 TL66), with Chiron.

And then, a few days later, the astronomers discovered a second icy mini planet out there,

19308 (1996 TO66).

For more information on both of these, as well as an ephemeris for each, go toICY MINI PLANETS

After Chiron, there was a lag of many years with no new bodies discovered in that part of the solar system, so it was quite a shock when, in the early 1990's, a new body, very similar to Chiron, was found! (There are 97 Centaurs found so far, and there may be many more.) Read all about the Centaurs:
